How can we have sexual intercourse without her hurting?

one word. handcuffs. or is that two? just attach her to the bed so she cant stop. your sex life will have new life. i tried duck taping a pillow around my cock but that went horribly wrong. turns out she still has feathers from it in her snatch that cant be surgically removed without permanently ending her sex life. also, after a long time of experimenting i find bacon grease an excellent lubricant.
